spinal tract, any one of the ascending (sensory) and descending (motor) pathways for sensory or motor nerve impulses that is found in the white matter of the spinal cord.
This system can be divided into two parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord, which function to receive, process, and send information to the PNS. The PNS consists of cranial nerves, spinal nerves, and billions of sensory and motor neurons. The primary function of the peripheral nervous system is to serve as a pathway of communication between the CNS and the rest of the body. While CNS organs have a protective covering of bone (brain-skull, spinal cord - spinal column), the nerves of the PNS are exposed and more vulnerable to injury. Types of Cells
